BACKGROUND

Long-chain omega-3 fatty acids, such as EPA and DHA, are well established in the treatment of hypertriglyceridemia (HTG) and have beneficial effects upon other risk factors associated with chronic heart disease, such as hypertension and a prothrombotic state. Omega-3 fatty acids, such as EPA and DHA, may also regulate immune functions, insulin action, neuronal development, and visual function. Further, omega-3 fatty acids are generally well-tolerated, without giving rise to severe side effects. However, due to their limited biological effects upon other cardiovascular risk factors, such as lowering LDL-cholesterol, there is a need to develop new omega-3 fatty acid derivatives with improved biological effects. Rossmeisl and coworkers have studied the biological effects of omega-3 fatty acid derivatives, such as alpha-substituted EPA and DHA derivatives. See Rossmeisl et al. (Obesity (2009) 17: 1023-1031).

International Patent Application Publication No. WO 2010/128401 discloses that 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid favorably influences lipid profiles and inhibits the development of atherosclerosis in the APOE*3Leiden.CETP transgenic mouse model. Specifically, 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid decreased total cholesterol and increased HDL cholesterol as compared to a control. It also decreased atherosclerotic lesion areas in the aorta as compared to a control. Those results demonstrate that 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid and its derivatives may be useful in the prevention or treatment of various conditions, such as inflammation, hyperlipidemic conditions, obesity, fatty liver disease, atherosclerosis, peripheral insulin resistance, and/or diabetic conditions. Reference is made to pages 54-58 of WO 2010/128401 and pages 14-16 of WO2012/059818 describing the biological testing of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid and the corresponding Figures mentioned therein.

To be effective in such prevention or treatment regimes, the active ingredient, 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof must reach its biological target. Evidence suggests, however, that such targeting is complicated by enzymes that interconvert long chain fatty acids and alcohols in vivo. Moreover, the carboxylic acid functional group of fatty acid molecules targets cellular binding, but this ionizable group may hinder the molecule from crossing the cell membranes, such as that of the intestinal wall. As a result, carboxylic acid functional groups are often protected as esters, which are then hydrolyzed by plasma enzymes. This process may not occur quickly enough in the blood and may predominantly occur in the liver, keeping the active ingredient from reaching its cellular target.

Ideally, a formulation will assist or support the active pharmaceutical ingredient (API) in reaching its target organ, in this case the liver, and also will improve the bioavailability of the API by increasing the portal vein uptake and improve the pharmacokinetics properties leading to enhanced benefit-risk properties of the API due to lower systemic exposure and thus reduced risk of systemic adverse events.

Documents such as WO 2010/103402 and US 2011/0054029 disclose fatty acid compositions comprising surfactants but do not specifically disclose 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid. Even though both documents describe formulations stated to improve bioavailability of omega-3 fatty acids, such as EPA and DHA, no teaching is given with respect to formulations improving the pharmacokinetic properties, such as lack of gender differences, low individual variability or dose proportional exposure. Nor do the above mentioned patent applications address the problem of achieving food independent bioavailability of the active ingredients.

Thus, there remains a need for compositions comprising 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof that improve or enhance solubilization, digestion, bioavailability, and/or absorption in vivo, while maintaining the ability for 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof to cross cell membranes and reach its biological targets. Furthermore, there remains a need for a composition that has improved pharmacokinetics properties, such as lack of gender differences, low individual variability or dose proportional exposure, and does not exhibit food effects, of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof, in a desirably fashion.

Such dispersions can be characterized as nano- or microemulsions. For example, upon delivery, the compositions are thought to produce dispersions or emulsions with gastric or other physiological fluids and are thus considered to be self-nanoemulsifying drug delivery systems (SNEDDS) or self-microemulsifying drug delivery systems (SMEDDS).

Absorption of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof is enhanced by administering to a human a pharmaceutical composition comprising from 5% to 60% by weight of the total composition of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof; from 15% to 60% by weight of the total composition of a medium-chain triglyceride; and from 10% to 60% by weight of the total composition of a nonionic surfactant, which is a self-nanoemulsifying drug delivery system (SNEDDS) or self-microemulsifying drug delivery system (SMEDDS) and forms an emulsion in contact with aqueous media as disclosed herein. In another embodiment absorption of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid is enhanced by administering to a human a pharmaceutical composition comprising from 5% to 60% by weight of the total composition of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid; from 15% to 60% by weight of the total composition of a medium chain triglyceride; and from 10% to 60% by weight of the total composition of a nonionic surfactant, which is a SNEDDS or SMEDDS and forms an emulsion in contact with aqueous media as disclosed herein.

Thus, in at least one embodiment, the MCT oil is derived from capric acid and caprylic acid. In at least one embodiment the MTC oil comprises between 50 and 80% caprylic acid and between 20 to 50% capric acid. In one embodiment the MTC comprises from about 50 to 60% caprylic acid and about 40 to 50% capric acid, such as for example about 56% caprylic acid and about 44% capric acid.

SMEDDS/SNEDDS/SEDDS

The compositions of the present disclosure may be in a form of a self-nanoemulsifying drug delivery system (SNEDDS), self-micromulsifying drug delivery system (SMEDDS), or self-emulsifying drug delivery system (SEDDS), wherein the compositions form emulsions in an aqueous solution.

Examples of aqueous solutions include but are not limited to water, gastric media, and intestinal media.

Without being bound by theory, it is believed that the disclosed SNEDDS, SMEDDS, or SEDDS compositions form an emulsion upon contact with gastric and/or intestinal media in the body, comprising micelle particles. The emulsion may, for example, provide for increased or improved stability of the 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof for uptake in the body and/or provide increased or improved surface area for absorption. SNEDDS, SMEDDS and SEDDS may thus provide for enhanced or improved hydrolysis, solubility, bioavailability, absorption, or any combinations thereof of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof in vivo.

The SNEDDS, SMEDDS or SEDDS compositions presently disclosed may comprise a particle size, that is a particle diameter, ranging from about 5 nm to about 5 μm. For example, in some embodiments, the particle size ranges from about 5 nm to about 1 μm, such as from about 10 nm to about 750 nm, from about 50 nm to about 500 nm, or from about 150 nm to about 350 nm, as measured using a Malvern Zetasizer (Malvern Instrument, Worcestershire, UK) with particle size measuring range of 0.6-6000 nm and Zeta potential of particle range of 3 nm-5 μm.

Methods or Uses

The present disclosure further provides for a method of treating, preventing, and/or regulating at least one health problem in a subject in need thereof comprising administering to the subject a composition comprising 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, as an ester derivative, or a pharmaceutically acceptable salt thereof; a triglyceride; and a surfactant, wherein the at least one health problem is chosen from a disorder responding to the activation or modulation of at least one of the human peroxisome proliferator-activated receptor (PPAR) isoforms α, γ or δ; a dyslipidemic condition, for example hypertriglyceridemia (HTG); dyslipidemia; mixed dyslipidemia; elevated triglyceride levels, non-HDL cholesterol levels, LDL cholesterol levels, and/or VLDL cholesterol levels; the increase of HDL cholesterol; obesity or an overweight condition; the reduction of body weight and/or for preventing body weight gain; a fatty liver disease, for example non-alcoholic fatty liver disease (NAFLD); an inflammatory disease or condition; atherosclerosis; peripheral insulin resistance and/or a diabetic condition; type 2 diabetes; and the reduction of plasma insulin, blood glucose and/or serum triglycerides.

Because the active ingredient is highly lipophilic and thus demonstrates very low water solubility, several experiments were performed to find optimal solvents or SMEDDS that would increase the solubility and/or form stable emulsions in water and bio-relevant media, such as gastric juice and intestinal content. Surprisingly, the inventors found that compositions within certain ranges of components could form emulsions at fast or medium speed—in such a way that emulsions could be formed in an in vivo setting. In addition, compositions according to the present disclosure form both micro- and nano-emulsions with particle size as low as 10 nm to 150 nm, that were stable in both gastric juice and intestinal fluid. Thus, the presently disclosed compositions may be used in a pharmaceutical formulation with or without enteric capabilities. A SNEDDS formulation was even shown to improve the in vivo bioavailability by at least 30%. This improvement was demonstrated by a predominant increase in the Port-vein uptake, thereby possibly increasing the pharmacological activity by increasing liver uptake as compared to increased lymph uptake, and thus without increasing the systemic adverse effects.

The present disclosure is also directed to a self-microemulsifying drug delivery system (SMEDDS), self-nanoemulsifying drug delivery system (SNEDDS), or self-emulsifying drug delivery system (SEDDS) comprising 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof; a triglyceride; and a surfactant, wherein the composition forms an emulsion in an aqueous solution for the treatment and/or regulation of at least one health problem chosen from a disorder responding to the activation or modulation of at least one of the human peroxisome proliferator-activated receptor (PPAR) isoform α, γ or δ; a dyslipidemic condition, for example hypertriglyceridemia (HTG); dyslipidemia; mixed dyslipidemia; elevated triglyceride levels, non-HDL cholesterol levels, LDL cholesterol levels, and/or VLDL cholesterol levels; the increase of HDL cholesterol; obesity or an overweight condition; the reduction of body weight and/or for preventing body weight gain; a fatty liver disease, for example non-alcoholic fatty liver disease (NAFLD); an inflammatory disease or condition; atherosclerosis; peripheral insulin resistance and/or a diabetic condition; type 2 diabetes; and the reduction of plasma insulin, blood glucose and/or serum triglycerides.

In one embodiment, the present disclosure provides for a method of treating at least one health problem in a subject in need thereof, comprising administering to the subject a composition comprising a pharmaceutically-effective amount of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid, an ester derivative, or a pharmaceutically acceptable salt thereof; a triglyceride; and a surfactant. In some embodiments, the method treats at least one of elevated triglyceride levels, non-HDL cholesterol levels, LDL cholesterol levels and/or VLDL cholesterol levels. For example, the method may reduce triglyceride levels from about 30% to about 80%, such as from about 40% to about 70%, such as from about 40% to about 60%, or from about 30% to about 50%, in a subject with elevated triglyceride levels.

In at least one embodiment, at least one disease or condition is atherosclerosis.

The following examples are intended to illustrate the present disclosure without, however, being limiting in nature. It is understood that the skilled artisan will envision additional embodiments consistent with the disclosure provided herein.

EXAMPLES General Procedures

Different compositions were prepared as described in Tables 10-15. The active ingredient is 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid. To prepare the compositions, the components were mixed according to the Tables identified below on a weight to weight basis. The compositions were visually inspected after mixing and again after being stored for 24 hours at room temperature. Under the Composition heading, a “clear” designation represents a transparent homogenous mixture; an “unclear” designation represents a nonhomogenous mixture, where some turbidity can be observed by visual inspection. The degree of turbidity was not determined.

All clear compositions were emulsified in the specified aqueous medium, by adding the aqueous medium (2 ml) to approximately 100 mg of the composition. The composition of the gastric media is shown in Table 8, and the composition of the intestinal media is shown in Table 9.

TABLE 8 Composition of Gastric Media. Gastric Media Bile salts, Porcine (mM) 0.08 Lechitin (mM) 0.02 Sodium chloride (mM) 34.2 Pepsin (mg/ml) 0.1 pH 1.6 (adjust with 1M HCl) Osmolarity (mOsm/kg) 120

TABLE 9 Composition of Intestinal Media. Intestinal Media Bile salts, Porcine (mM) 5 Phospholipids, LIPOID S PC (mM) 1.25 Trizma maleate (mM) 2 Na⁺ (mM) 150

The outcome of the emulsification was determined by visual inspection approximately 30 minutes after mixing. A majority of the compositions formed milky emulsions immediately after mixing. Emulsions that stayed milky and homogenous after 3 hours are described as “milky,” under the Emulsion heading. Emulsions that separated or became nonhomogenous or where oil drops were observed are described as “separates,” under the Emulsion heading.

Selected emulsions were further characterized by determining the particle size. Particle size was measured using a Malvern Zetasizer (Malvern Instrument, Worcestershire, UK) with particle size measuring range of 0.6-6000 nm and Zeta potential of particle range of 3 nm-10 μm.

The microemulsions formed can then be tested regarding distribution of API into the micellar, lipid and pellet fraction under lipolytic conditions. In Vitro lipolysis experiments was performed with a SMEDDS formulations, exemplified by formulation No. 27, in a biorelevant fasted state intestinal media. This SMEDDS formulation will increase the concentration of the compound in the micellar phase by more than 50%, compared to a standard oil formulation. Thus, this SMEDDS increases the rate and extent of amount available for absorption in an in-vivo situation.

The results are given in Table 10 below. Emulsions of Composition Nos. 9, 14, 17, 18, 22, 23, 24, 25 and 27 were formed using both gastric media and intestinal media as the aqueous media (in separate experiments). Particle size distribution for Composition Nos. 1-8 in water is shown in FIG. 1. Particle size distribution for Composition Nos. 9, 14, 17 and 18 in gastric and intestinal media is shown in FIG. 2.

Increasing the LCT fraction to 235 resulted in non-homogeneous pro-concentrates. Emulsions of Composition Nos. 62-65 were formed using water as the aqueous medium. The composition of the preconcentrates are shown in Table 14 and the particle size distributions for the emulsions formed in water are shown in FIG. 7.

Preparation of Magnesium 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoate

(2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid (3.74 g) was mixed with MgCO₃ (420 mg, Sigma-Aldrich, Catalog no. M7179). Water (2.0 ml) was added and the mixture was stirred with mechanical stirring at room temperature (RT) overnight. CO₂ develops and thick homogeneous pasta is formed. Ethanol (20 ml) was added to the reaction flask under stirring. The magnesium salt formed from (2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid goes into solution upon addition of ethanol. The solution was filtered and evaporated to dryness in vacuo. The crude viscous oil was evaporated two times with 96% ethanol to remove traces of water. The oil was stored under nitrogen at room temperature and does not change in color over after storage for several weeks.

Preparation of Compositions

Compositions were prepared by mixing the components shown for each sample in Table 16. The compositions were scored as unclear (separates into phases in short time), cloudy (close to being transparent, and do not separate into phases) and clear (homogenous transparent pre-concentrates). The compositions contained Tween 80, MCT oil (Miglyol 812N) and the magnesium salt of (2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid. As shown in Table 16 compositions forming clear preconcentrates are formed comprising about 20-50% by weight of the total composition of API, about 45-60% by weight of the total composition of MCT oil and about 5-25% by weight of the total composition of Tween 80. The best compositions were formed having about 50% by weight of the total composition of MCT oil, about 30% by weight of the total composition of magnesium salt of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid and about 20% by weight of the total composition of Tween 80.

Example 8: Improvement of Portal Vein Uptake

The absorption profile of a formulation including Tween 20 (40 wt %), Miglyol 812N (30 wt %) and 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid (API, 30 wt %) was investigated. The API was mixed with the other components of the composition as described under “General procedures.” The formulation used in this example corresponds to composition No. 27 of Example 1. The absorption was studied in groups of 4 male Sprague-Dawley rats following administration of a single oral dose of API at 50 mg/kg/body weight.

Rats were fasted overnight prior to use and are supplemented with 2 ml/rat 0.9% saline 30 min before dosing. The formulation was administered by oral gavage and blood was withdrawn via portal vein catheter and lymph fluid via mesenteric lymph duct. Samples were obtained at indicated time points post administration up to 24 hour. The API concentration in both plasma and lymph were analyzed.

Amount absorbed per time unit was determined as AUC times flow, see Table 17.

TABLE 17 Portal vein and mesenteric lymph absorption after single oral dose of API at 50 mg/kg/BW in SD rat API in Tween 20 and Miglyol 812 T_(max) Formulation C_(max) (μg/mL) AUC * flow (h) Portal vein 19 715 2 Mesenteric lymph 7.7 66 4

It is concluded that the formulation provided much higher uptake by the portal vein as compared with lymphatic route. Thus, the systemic exposure is reduced and as a result may also reduce possible systemic side effects of the API.

Example 9: Improved Bioavailability

The pharmakinetic profile of two different formulations (corn oil or Tween 20/Miglyol 812) of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid (API) was studied in groups of 4 male Gottingen minipigs following administration of a single oral dose at 276 mg/animal (in corn oil) or 309 mg/animal (Tween 20/Miglyol 812 formulation). The formulation according to the present disclosure included Tween 20 (40 wt %), Miglyol 812N (30 wt %) and API (30 wt %). The API was mixed with the other components of the composition as described under “General procedures.” The composition in this example corresponds to composition No. 27 of Example 1. Both formulations were administered to the minipigs by oral gavage.

Plasma levels of API increased to reach a maximum between 1 and 3 hours post-dose with both formulations (Table 18). Plasma concentrations then decreased to low or undetectable levels at the last time-point of 36 hours after dosing. The formulation of API in Tween 20 and Miglyol 812 showed a 56% improvement of bioavailability compared to that of API in corn oil.

TABLE 18 Pharmacokinetic parameters of API after a single oral administration to minipigs Dose C_(max) Relative AUC_(0-24 h) T_(max) t_(1/2) Formulation (mg/kg) (μg/mL) (μg · h/mL) (h) (h) API in corn oil 15.5 1.97 1 2.8 10.2 API in Tween 20 17.3 3.82 1.56 1.3 9.11 and Miglyol 812N

For the formulation according to the present disclosure the absolute systemic bioavailability was determined to be 32% relative to an intravenous administration whereas total amount of API related material excreted by the urinary route was 60%.

It is concluded that the formulation according to the present disclosure improved both systemic and total bioavailability most probably by improving absorption via the portal vein.

Example 10: Improvement of Food Effect

Phase 1 study of 2-((5Z,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenyloxy)butanoic acid (API) assessing the safety, tolerability, PK, and pharmacodynamics (PD) have been performed in healthy individuals. Each group consisted of 6 healthy subjects. The formulation according to the present disclosure included Tween 20 (40 wt %), Miglyol 812N (30 wt %) and API (30 wt %). The API was mixed with other components of the composition as described under “General procedures.” The formulation of this example corresponds to composition No. 27 of Example 1. The premix was filled into capsules and administered orally to humans.

Data reported demonstrate that the API is rapidly absorbed into the blood stream with mean T_(max) values of approximately 1 to 2 hours in healthy male and female subjects receiving single doses. The food effect study carried out, with a minimum of 10 days intervene before each dose, demonstrated that there is no significant food effect on the bioavailability of the API using the SMEDDS formulation according the present disclosure. T_(max) was delayed by approximately 1.5 hour when the SMEDDS formulation was co-administered with food, see Table 19 and FIG. 9. FIG. 9 shows the arithmetic mean concentrations of API following single oral dose administration of 100 mg of API to healthy male subjects in fed and fasted state.

The API demonstrates both low solubility in water and low permeability. Thus, low bioavailability is expected. Surprisingly it is concluded that the SMEDDS composition according to the present disclosure decreases the food effect on the bioavailability.

Each dose group consisted of 6 healthy subjects. The initial dose of API received was 5 mg, and the maximum dose of API was 600 mg. The API was mixed with other components of the formulations according to Table 20, the premix was filled into capsules and administered orally to humans.

TABLE 20 Composition of API in capsules Amount API Miglyol 812 Tween 20 (mg) (wt %) (wt %) 5 42 56 50 36 49 100 30 40

A minimum of 10 days intervene before each dose escalation. Escalating doses are administered to the groups sequentially. Exposure based on maximum plasma concentration (C_(max)) and area under the curve 0 to 24 hours (AUC₀₋₂₄) increased in a higher than dose-proportional manner between 5 to 600 mg. FIG. 10 shows arithmetic mean concentrations of API following single oral dose administration of 5, 20, 50, 100, 150, 200, 400 and 600 mg to healthy subjects.

It is concluded that the SMEDDS formulation according to the present disclosure may provide dose independent linear pharmacokinetics.

Example 11: Demonstrating Low Individual Variability in Pharmacokinetics

Each dose group consisted of 6 healthy subjects. The initial dose API received was 5 mg, and the maximum dose was 600 mg. Data presented here are with an API dose of 600 mg. This formulation included Tween 20 (40 wt %). Miglyol 812N (30 wt %) and API (30 wt %). The API was mixed with other components of the composition as described under “General procedures.” The formulation for this example corresponds to composition No. 27 of Example 1. A minimum of 10 days intervene before each dose escalation. Escalating doses were administered to the groups sequentially. Exposure based on maximum plasma concentration (C_(max)) and area under the curve 0 to 24 hours (AUC₀₋₂₄) demonstrated unexpectedly low individual variability in pharmacokinetics with a % CV (relative variability) of approximately 10 and 15% respectively. FIG. 11 demonstrates plasma concentrations of API for all subjects following a single oral dose administration of 600 mg to healthy male subjects.

It is concluded that the SMEDDS formulation according to the present disclosure may result in low individual variability in pharmacokinetics.
